Description
Summary:We theoretically investigated the influence of pumping intensity radiation on the active medium of a neodymium:glass microlaser. The pumping radiation in the neodymium:glass microlaser causes heating of the active medium to the softening temperature. The time necessary for the heating is estimated; it changes from fractions of nanoseconds to hundreds of microseconds. When the radius of the neodymium:glass microparticle is larger than 40-50 microm, its heating by pumping radiation can lead to breakage of the lasing inside the microparticle.
